Joint Oireachtas Committee on Climate Action

Engagement with the Commission for Regulation of Utilities

Mr. Jim Gannon:

We observe and monitor the level of network tariffs that will be charged to consumers in a given year across the segments. That is the infrastructure required to supply electricity and operate and maintain those wires. We would understand the single electricity market and the cost of capacity in a given year that is being supported through capacity payments. We observe the different costs relating to the wholesale market, which is set by different types of plant at different points in time, which can change over the course of hours in a single day, be they wind, coal or gas. In a given year, we can see other charges, such as those relating to the single electricity market operating charges and those relating to imperfections in the markets, where, for example, the market assumes a wire is ready to be used even though it is not. However, I am not sure the analysis has been done to try to match precisely how those charges in each and every case are attributed to a specific consumer and the influx of that specific consumer back to all of those ranges of charges.
